首先上一下效果图

布局比较简单 就是一个button以及textView 下面我就直接放代码吧。

            package daviddatepickerdemo.qq986945193.com.daviddatepickerdemo;

             import java.util.Calendar;

            import android.app.Activity;

            import android.app.DatePickerDialog;

            import android.app.Dialog;

            import android.os.Bundle;

            import android.view.View;

            import android.view.View.OnClickListener;

            import android.widget.Button;

            import android.widget.DatePicker;

            import android.widget.TextView;

/**

* 时间选择器

*/

public class MainActivity extends Activity {

            int mYear, mMonth, mDay;

            Button btn;

            TextView dateDisplay;

            final int DATE_DIALOG = 1;

        @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        btn = (Button) findViewById(R.id.dateChoose);

        dateDisplay = (TextView) findViewById(R.id.dateDisplay);

        btn.setOnClickListener(new OnClickListener() {

            @Override

            public void onClick(View v) {

                showDialog(DATE_DIALOG);

            }

        });

        final Calendar ca = Calendar.getInstance();

        mYear = ca.get(Calendar.YEAR);

        mMonth = ca.get(Calendar.MONTH);

        mDay = ca.get(Calendar.DAY_OF_MONTH);

    }

    @Override

    protected Dialog onCreateDialog(int id) {

        switch (id) {

            case DATE_DIALOG:

                return new DatePickerDialog(this, mdateListener, mYear, mMonth, mDay);

        }

        return null;

    }

    /**

    * 设置日期 利用StringBuffer追加

    */

    public void display() {

        dateDisplay.setText(new StringBuffer().append(mMonth + 1).append("-").append(mDay).append("-").append(mYear).append(" "));

    }

    private DatePickerDialog.OnDateSetListener mdateListener = new DatePickerDialog.OnDateSetListener() {

        @Override

        public void onDateSet(DatePicker view, int year, int monthOfYear,

                              int dayOfMonth) {

            mYear = year;

            mMonth = monthOfYear;

            mDay = dayOfMonth;

            display();

        }

    };

}

xml 布局：

?xml version="1.0" encoding="utf-8"?

<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:gravity="center"

    android:orientation="vertical">

    <TextView

            android:id="@+id/dateDisplay"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:text="时间显示"/>

    <Button

            android:id="@+id/dateChoose"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:text="选择日期" />

</LinearLayout>
